| LeftJoinTSource, TKey, TResult(IEnumerableTSource, IEnumerableTSource, FuncTSource, TKey, FuncTSource, TResult, FuncTSource, TSource, TResult) | Performs a left outer join on two homogeneous sequences.
            Additional arguments specify key selection functions and result
            projection functions. | 
| LeftJoinTSource, TKey, TResult(IEnumerableTSource, IEnumerableTSource, FuncTSource, TKey, FuncTSource, TResult, FuncTSource, TSource, TResult, IEqualityComparerTKey) | Performs a left outer join on two homogeneous sequences.
            Additional arguments specify key selection functions, result
            projection functions and a key comparer. | 
| LeftJoinTFirst, TSecond, TKey, TResult(IEnumerableTFirst, IEnumerableTSecond, FuncTFirst, TKey, FuncTSecond, TKey, FuncTFirst, TResult, FuncTFirst, TSecond, TResult) | Performs a left outer join on two heterogeneous sequences.
